C includes operators to manipulate memory at the bit level. This is useful for writing low level hardware or operating system code where the ordinary abstractions of numbers, characters, pointers, etc… are insufficient - an increasingly rare need. Bit manipulation code tends to be less “portable”.

Data-encapsulation is key to the functionality of many high level or later generation programming languages such as C++ and Java. It is simply a means of creating “containers” called objects, and holding multiple variables of varying data types called member variables inside of those containers. C++ offers three methods of data-encapsulation; struct, union and class. This is where C++ become object oriented.

Object oriented programming (OOP) have taken the best ideas of structured programming and combined them with several powerful new concept that encourage you the approach the task of programming in a new way.
